Now that I've been several times, I think Bevvy is my favorite Old Town spot. Let me start by saying I am a little biased because I am a Wolverine Fan, and this is the official U of M bar -- so I frequent Bevvy to watch U of M football games. That being said, I LOVE the music, especially because it's often old school hip hop/r&b mixed with a little new school - which is totally my thing.
The bar is in the center of the establishment. There is high top and booth seating inside and hightop seating outside. I almost always choose to sit outside so I can people watch. The only downside of outdoor seating is smoke. They have several fun, yard games for entertainment too.
Food is good and depending on when you go they have brunch, appetizers/snacks, and other sandwich and bar menu options. One of my favorite items is the popcorn served with bits of BACON...yum. How can you ever go wrong with bacon?! Service is usually pretty good although depending on the crowd or event you'll definitely have a wait for food/drinks. Seating is first come first serve but I always seem to be able to find a nice place to sit comfortably.
What I love most about Bevvy is the chill atmosphere and great music.
